  23. Data Actions Get - features (WFS, GeoJSON), Images (WMS, Tiles) Create/Edit - OL features Post - geometry (text), attributes (forms) Admin GeoJSON PHP/ CI/JQuery PHP/ CI WFS WMS Map TileCache MapServer Users PHP/ CI JS/ JQuery Database OGR Forms PHP/ CI
  24. More Tools Admin - DataTables.js Exports - PHPExcel, Wkhtml2pdf, pgsql2shp
  25. Directions to watch for CartoDB Google MapMaker/Fusion Tables Ushahidi GeoDjango UTF Grids
  26. Tools can do most anything Is the crowd willing (and able…)? We’re all too busy Make it easy and focused Use flexible tech
